Mark Ballas returned
to Dancing With the Stars on Monday, but not in the way fans were expecting.

The former DWTS pro, who left the show this season to star as Frankie Valli in the Broadway production of Jersey Boys, hit the stage in character as the Four Seasons crooner for DWTS' Showstoppers Night.

Ballas and his Jersey Boys co-stars sang "December, 1963 (Oh, What a Night)," while Derek Hough and his partner, Marilu Henner, performed a fun, lighthearted samba.

After their dance --which earned a score of 36 out of 40 for the pair -- Hough took time to hug it out with his longtime bestie before going to the judges' table for feedback. It was another adorable moment in their bromance.

Back in September, Ballas spoke with ET and opened up about getting the opportunity to star in the long-running hit, sharing, "I've been a fan of this show since it came out."

"This is the last run, and I'm going to be able to play the final Frankie on Broadway," Ballas marveled. "So this is incredible. I'm super excited." Check out the video below to hear more.
